Speciication of Letters Patent.

To all whom t may concern:

Be it known that I, WILLIAM Coon, a citizen of the United States, and resident of the borough of Manhattan, in the city and A further object is to provide m eanssup ported from the building u rights for truing the mold plates, toget er with means carried by themold plates for retaining them in the position in which they are forced by the truing means.

A further object 1s to provide means removably carried by the mold plates for partially filling the space between the said plates so as to produce a honeycombedwall.A

A further object is to provide projections on the inner face of the mold plates for creasing the wall to produce an eii'ect in imitation of a wall composed vof stone blocks.

Astill further object isl to provide certain improvements in the form, construction and arrangement of the various parts whereby the above objects may be effectively carried out. A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 represents a side elevation of a portion of a wall with my apparatus thereon, parts being broken away to show the interior, Fig. 2 represents an end view. of the parte shown in Fig. 1, a portion vbeing broken away, Fig. 3 represents a top plan view of the parts shown in Fig. 1, Figs. 4, 5 and 6 represent detail end, top plan and side views, respectively, of the means for .sup- .porting the mold plates from ,the building uprights, together with means for adjusting the mold plates. Figs. 7, 8 and. 9 .represent detail end, top plan and side views, re-

spectively, of one of .the removable cores in position on the mold plate, Figs. 10 and 11 are *detail end and side views, respectively, of one of the -clamps carried by the mold plates for holding them in the position in which they are forced by. the adjusting means, Figs. 12 and 13 arevdetail side and top plan views, respectively, of a right angle section of the mold plates, and Fig. 14 is a detail v view of the inner face of the 1 outer mold plate.`

The building uprights are'indicated by 1 and have enlarged bed plates 2 at their lower ends. The uprights are shown,y in

.the present instance, as tubular; gas pipe being al very convenient material for this use. Yokes 3 are fitted to slide longitudinally on the uprights, and are provided with set screws 4 for securing them in any desired adjustment thereon. Depending from these yokes at opposite sides of the uprights, are hangers 5, which'are arranged to beadjusted 'on-the yokes laterally with respect to the upri hts, and-may be secured in any 'desired position on the yokesbythe set screws 6. These hangers are ladapted to receive the outer ends.- of screw bolts 7, set in the mold plates 8, for securing the plates to the hangers; and are'also provided with adjusting screws 9 for truing the mold plates and kee ing them perfect-ly plumb. f

The mold p ates 8 are preferably composed of sheet iron and are provided with angle irons bolted along their upper and lower edges. These plates may be made of any desired length by bolting the sections together, as indicated at 10. The outer mold plate is provided, alon its inner face,

with upper and lower projections 11, 12,-

for producing creases-'in the wall molded against them. -The upper projection' has Y' the cross sectional shape of a right-angled triangle, while the lower projection has'ther rest on the bevel thus formed, while itsupper face forms the, other bevel of the crease asthe next course of wall is molded.

Tapered cores 13 are secured .to crossbars 14, which bars are adapted to be removably attached to the angle irons of the mold plates 8, at any desired positions along said plates, by means of clips 15, and thumb nuts 16. The bars 14: serve the double purpose of supporting the cores 13 and also holding the mold plates against spreading when it is desired to tamp the wall as it is molded. These cores are intended to project down'- wardly and partially ill the space between the mold plates, so as to leave holes in each course as it is molded, and thus produce a honeycombed wall.

Tapered plugs 17 are provided for closing the tops of the holes in each course, so that the material .used in constructing the course next above will not fill the holes in the lower course.7 Clamps for holding the on the mold plate. The lower cross bar 20 lco is provided with a pin and hole adjustment with the side bars 18, and the upper cross bar 19 is provided with a pin and-hole adjustment with one of the side bars 18 and a screw threaded adjustment with the other of the side bars 18. By leaving the lower cross bar 20 in a fixed adjustment, the lower ends of the side bars may be swung inwardly by adjusting' the upper cross bar 1,9, thus producing the desired pressure on the mold plates, and assisting the adjusting screws 9 in keeping the said plates plumb. If desired, wires 22 maybe strung from upright'to upright between each course of wall, for lending strength to the completed structure.

In operation, the uprights 1 are placed in the desired location, and anchored by any suitable means, such, for instance, as a foundation layer of concrete. The yokes 4 are then placed on the uprights and secured in proper position for molding the iirst course. The mold plates are then secured to the hangers 5 and trued up by the screws 9, and clamped in place by the clamps comprising the members 18, 19, 20, 21. The wire 22 may be strung in place, and the cores 13 secured at proper points on the mold plates. The concrete is then poured in between the mold plates up to the to thereof. After the concrete has hardene vthe cores 13 are removed and the holes left by them closed by means` of plugs 17. The

vwhole molding apparatus may then be raised with the yoke 4 along the uprights and secured in place for molding the next course of wall, when the operation may be repeated. The uprights 1 are intended to rousses remain permanently in the wall to give it strength, and they thus perform the function of regular building uprights, as well as suppo-rting means for the mold apparatus.

4 By using the cores. 17 I may produce a honeycombed wall thus saving a consldervable amount o-f building material. These cores may be spaced at any desired intervals one from the other, in order to produce a greater or lesser number of holes in the wall. The adjustment of the hangers 6 on the yokes 4 lis provided for molding walls of different thicknesses.

While I have shown the projections on the inner face of the outer 'mold plate las tbeing elongated and having the cross sectional form of triangles, vit is to, be under stood that I may use any kind, of projections of any length and of any cross section in place of the one shown; or I may omit the projections entirely and.' use the'mold plates plain; or with merely roughened faces to make a wall 'having an exterior surface in imitation of the surface of stone.

It is obvious that certain changes may be resorted to in the form, construction and arrangement of the various parts of my device without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the form herein shown and described. i

What I claim isz-- 1. In apparatus of the character described havingbuilding uprights, mold plates provided with lateral extensions at their tops, means for supporting the plates from the building uprights, means for truing the plates also supported from the building uprights independently of the plates, removable cores carried by the plates for partially filling the space between them, said cores being provided with clips tted to kengage the said lateral extensions of the plates for securing the cores in position thereon. j

2. In apparatus of the character described having building uprights, mold plates provided withalateral outward extensions at their lower edges, means'for supporting the plates from the building uprights, means for truing the plates also supported from the building uprights, and clamps for holding the plates in their trued position, the said clamps being provided with blocks fitted to engage the said lateral extensions of the plates, whereby the clamps may be carried by the plates.

3. In apparatus of the character described having building uprights, mold plates provided with lateral outward extensions at their lower edges, means exterior to the plates for supporting them from the building uprights, means for truing the rights and independently ofthe plates, and

clamps for holdin the plates in their trued presence of two witnesses, this seventh day positions, the 'sai clamps being provided of May 1909. with blocks fitted to engage the lateral extensions of the plates, whereby the clampsA WILLIAM COOK' 5 are carried by the plates. Witnesses:

In testimony that I claim the foregoing F. GEORGE BARRY,

as my invention, I have signed my name in HENRY THIEME.
